21、ive). WARNING - Equipment, materials and abrasives used for surface preparation can be hazardous if used carelessly. Many national regulations exist for those materials and abrasives that are considered to be hazardous during or after use (waste management), such as free silica or carcinogenic or to

22、xic substances. These regulations are therefore to be observed. It is important to ensure that adequate instructions are given and that all required precautions are exercised. 1 Scope This part of IS0 11 126 specifies requirements for olivine sand abrasives, as supplied for blast-cleaning processes.

23、 It specifies ranges of particle sizes and values for apparent density, Mohs hardness, moisture content, conductivity of aqueous extract and water- soluble chlorides. The requirements specified in this part of IS0 11 126 apply to abrasives supplied in the “new“ condition only. They do not apply to a

24、brasives either during or after use. Test methods for non-metallic blast-cleaning abrasives are given in the various parts of IS0 11127. NOTES 1 for non-metallic abrasives is given in annex A. Information on commonly referenced national standards niques are described in IS0 8504-2:1992, Preparation
